To all whom it may concern Be it known that I, lViLLIAM F. LITTLE,

citizen of the United Statesof America, re-

of the kind which has a neck or portion of reduced diameter at the top, in which the socket and a 'part'of the bulb are inclosed. However, the invention may be otherwise applied, the purposeheing to provide for convenient access to thesocket and the ends of the Wires.

Commonly the 'end of the conduit threaded and theupper end of theshade is provided with a nut or threaded boss to engage the thread; or the conduit may be provided with a flange spaced back from its edge and the lower portion of the conduit threaded to receive a nut or other threaded member, as a specially formed socket by means of which the shade is forced. up (against the flange. The end of the conduit ordinarilyenters'anv aperture in the hood and the hood is fastened to and supported by the conduit. The socket is alsosupported on the end of the conduit or in some similar inannerand is located within the neck at its upper end. The device is generally set up and the connections made as follows: A double length of wire is connected at its two ends with the terminals of thesocket and'threaded through the aperture in. the shade. The length of wire above the hood is then passed up the conduit and connected to the terminals provided for that purpose,

in the box where the conduit branches. The

shade is then fastened by any suitable inc-ans as described above, to the end of the conduit.

Under these cir 'uinstances, the only way to' get-attire socketfon purposes ofrepair or replacement, is to disconnect the wires at the box dud. draw them out of the condu t. Some types of fixtures are provided, in

which the Wires may be disconnected from snapsaun'fsocxhrnotified,

portion of the sleeve.

the sockets from below but even in this case 111 is very ditlicult to replace the socket when it has once been removed without disconnecting at the box, or someequivalent operation, as the ends of the wires are necessarily short and brittle. u

The object of the present invention isto provide a fixture of this general type, which may be applied to the end of any conduit by merely cutting a suitable thread thereon, and which is so constructed that the hood may be easily displaced and moved up the conduit to uncover the connecting-the wires. The socket is likewise supported so that it maybe conveniently removed and replaced. i

With this end in view, a sleeve oi-{boss is WILLIAM FoNTAIN E LITTLE, cr teria-mien. nnw'rronii, assassins-no QAME; MORE ENAMEL & novnnr co yiraur, cs a TIMon-n. Melwnenngea cannon-A.

socket without ,dis-

provided which is screw threaded internally toengage the lower end of the conduit and provided with a flange or other abutment at its lower end. Above the flange, the sleey'e is screw threaded externally hnd an internally threaded ring or nut is provided "to engage the thread on the outside of the sleeve, the shade or hood being provided with an aperture toreceive the threaded To set up the device, the ring or nut is first passed. on to the conduit and the shade is passed up the conduit beneath the nut,- the conduit extending through the aperture in the shade. The sleeve isthen screwed on to the end of tl'lHCOl'ltllllt its threaded end extending through the. aperture in the shade. and the nut "or threaded ring vis screwed down over the boss or' sleeve press ing the shade against thefflange thereon.

When it is desired to getlat the socket, this may be "ery con veniently done unscrewing the nut and slidingthe shade up the conduit, when free access may behad to the socket. v I I Iirthe preferred "form of my invention, the socket is supported on a bracket which con sistsof a ring to inclose tlie' sleeve.to which I have referrethand a pluralityof arms radiating from the ring. These armserejde flected downward and are provided their ends .=with gripper jaws adapted to e gage the socket, the latter beingpreferably' ofjthe type which consists of a cup .portionhay-ing a shoulder near the centerpf its outer sur-,

iace, andjis externally,threaded'above the shoulder, and provided with a flanged ring.

of copper or other metal having a thread'll to fit the thread of the cup. The arcua'te ends of the arms or grippers of the bracket are held between the shoulder of the cup and the flange of the ring. The upper end of the boss or sleeve may be passed through the ring which forms the support for-the bracket before it is screwed on the end of the conduit beneath'the shade, or the ring may be passed over the end of the conduit before the sleeve is applied thereto. Then the nut 18 screwed down against the shade to hold it in place the bracket is also clamped and held rigidly in place. To remove the socket it is only necessary after sliding the shade up the conduit to get it out of the way, to unscrew the socket ring, say half a turn, and remove the socket from the bracket; the arms being of thin sheet metal give sufficiently to permit convenient removal of the socket. Any other type of socket adapted to engage the gripper ends of the arms may be used.

In the accompanying drawing, I have illustrated a fixture embodying the'various features of my invention in their preferred form.

Figure 1 is a vertical central cross section of the device, Fig. 2 is an elevation. Fig. 3 is a view of the socket support or 30 bracket.

Referring to the drawings by the numerals which are placed thereon to indicate the various parts: The conduit 1 is preferably threaded at its lower end at 2 to receive the flanged sleeve 3 which is internally threaded to fit the conduit or-otherwise adapted to be fastened thereto, and externally threaded at 4 to receive the nut or ring 5 which is correspondingly threaded. The reflector shade or hood 6 which in its prefer-red form is made of 'metal and enameled to resist the weathenis apertured at 7 to receive' the reduced portion of the sleeve 3 above the flange. The aperture 7 is preferably provided with an eyelet or flanged sleeve 8 adapted to be gripped between the nut 5 and the flange or abutment 9 of the sleeve to protect the enamel of the shade and also to form a water-tight joint, the metal of the eyelet being sufiiciently soft to be easily compressed when the nut is tightened.

In the preferred form of,- my invention, the socket 10 is formed of a porcelain cup 11, haYlQJ, :a peripheral shoulder at 12, and is their led above the shoulder at 13. A thin metal r (194F714 threaded to engage the thread 13 closesylhe upper end of the porcelain cup,

This is flanged at 15 forming .a grip for-theends of the bracket arms as hereinafter describ" The socket is supported on the brac et 16 which consists of a ring 17 to engage the threaded portion of the sleeve and having a plurality of depending arms 18.- At the lowerend of each arm, is a flat arcuate gripping member 19 adapted 'to"engage the cup and to be gripped between the shoulder 12 and the flange 15. The arms 18 are. made of thin metal and may be easily flexed to permit the grippers 19' to engage and release the socket.

To set the device up for operation, the ring or nut 5 is first passed on to the conduit and moved up the same, the' gitlade being passed. on to.the conduit beneath the nut and I the ring 17 of the bracket '16 Heneath the shade.- The sleeve 3 may then be screwed on the end of the conduit, and the socket 1O engaged between the bracket arms 18 as described, the ring 14 being scitewed down against the gripper members: he shade is then lowered until it rests on he flange 9 and the nut 5 is engaged with the thread and screwed down until it engages the top surface of the shade, or engages and su iiciently compresses the eyelet 8, if such eyelet be used. The wires are of course con nected to the socket before it is seated and while the shade is raised.

It will be apparent that. if there is any necessity for repairing the socket or in any way manipulating it, it is only necessary to unscrew the nut 5 and raise the shade when the-socket is in full view and easily accessi' ble, and it may be conveniently removed by loosening the sleeve 14: disengaging the bracket arms 18. It may likewise be as conveniently replaced. It will also be apparent that this device may be applied to any conduit, the seating sleeve 3 being a portion of the fixtureand adapted tobe secured to any conduit by merely cutting" a thread thereon. Further there is no necessity for cutting or soldering the wires or for passing them in or out of the conduit when the socket is changed, repaired or inspected, as the wires and socket in the device described are as easily accessible as arethe sockets in the various fixtures used avith glass reflector shades or without a reflectorj I have thus described specifically a sin le embodiment of my invention in order tl at its nature and operation may be clearly understood.
